FREQUENCY METER ON FPGA - PLATE PCB
Producer: AVT
One of the measuring instruments frequently used in the laboratory is the frequency meter. The possibility of counting a series of pulses, determining their frequency or width are very important; especially when designing and testing digital systems.
Frequency meters can be performed in various ways - the following device is based on FPGA programmable devices (using the Verilog equipment description). An interesting feature is the dual reading imaging system, because it is possible to use LED or alphanumeric LCD displays for this. Both types can work simultaneously, it is possible to mount only one of them. For frequency and period measurements, the device is equipped with remote range change functions.
The device is especially recommended in the electronics studio, it will also work on the website.
Selected parameters:
- possibility to measure the frequency, period, duration of the pulse (with the stopwatch function) and the total number of pulses
- automatic change of ranges
- displaying measurement results on the LED display and / or alphanumeric LCD
- maximum resolution of 10 -6 Hz frequency measurement
- maximum time measurement resolution 10ns
- number of measuring inputs - 3
- input A: range 30Hz-100MHz, sensitivity <75mV, input impedance Z> 1.3Mom for f = 1kHz
- input B: range 70MHz-1GHz, sensitivity 10mV, input impedance Z = 50om
- C (digital) input: range 0Hz-150MHz
- power supply - 6Vac or 7.5Vdc
- printed circuit board and documentation included
